FIELD OF THE INVENTION

The present invention relates generally to hair washing sinks, and moreparticularly relates to a sink shaped to accommodate people with longhair.

BACKGROUND OF THE INVENTION

Each year, billions of dollars are spent on cosmetically-relatedproducts and services. Many of these products, for example, razors,tweezers, shampoos, conditioners, etc., are applied and used by thepurchaser in the privacy of their home. However, one aspect of personalgrooming—head-hair growth—cannot be easily and properly dealt withwithout help.

To maintain a well-groomed appearance, people usually present themselvesto salons and other hair-cutting businesses. In order for thehair-cutting professional to work with the hair in the best condition,the person's hair should be washed and free of dirt, oils, and products.For that reason, all hair salons have sinks for cleaning the client'shair prior to cutting or other treatments, e.g., dyeing. Most knownsinks generally used for washing hair in these salons are attached toand extend from a wall. To wash a person's hair, the person is placed ina chair with an angled back, which allows the person to place the backof his or her head/neck area on a front/lip portion of the sink.Unfortunately, due to the shallow bowl of standard sinks, those withlonger hair find that their hair simply lies at the bottom of sink bowland collects around and covers the drain area.

The shape/dimensions of these presently known sinks make it impossibleor very difficult to extend and properly clean longer hair. Most knownsinks provide no option for the operator, usually an employee at a hairsalon, for example, other than leaving the person's hair at the bottomof the sinks causing the hair to be bunched together in order to bewashed. As the hair is often in contact with the draining area at thelower portion of the sink during and after the cleaning process, therecently cleaned hair may become compromised by any debris or dirt thatwas previously removed and has accumulated. Further, when the hairaccumulates at the draining area of the sink it often causes a build-upof water.

Some prior-art sinks have attempted to incorporate deeper openings toaccommodate longer hair. As these known sinks are fixedly connected toand supported by wall, many operators find it difficult, if notimpossible, to reach down and wash the person's hair effectively andefficiently. Some known systems that allow a person's hair to extendinclude using a funnel-type apparatus that extends from the head/neckarea of the person down to the standard-sized sink opening. Theseapparatuses generally extend from a distance away from thestandard-sized sink to accomplish the hair extension. These systems usedfor washing a person with longer hair, however, disadvantageously takeup a significant amount of space, as the person must be a distance awayfrom the sink. Those apparatuses used in connection with sinks also aregenerally cumbersome and require storage when not washing a person withlonger hair. Moreover, these apparatuses generally require use incombination with a separate and distinct sink. In addition, many ofthese known hair washing apparatuses further require the person's hairto be pulled through an aperture in the funnel-type apparatus therebysecuring the apparatus to the top of the user's head, instead of thestandard head/neck area resting on a portion of the sink. Thoseaforementioned systems are undesirable and uncomfortable for the personhaving their hair washed as he or she is supporting the weight of thefunnel-type apparatus. Further, these systems are also undesirable asthe aperture that fits on the person's head is susceptible to leakingwhen confronted with water around the edges of the aperture.

Some known sinks try to circumvent these issues by integrating anautomated hair washing system for washing a person's hair. These knownsystems incorporate knobs, pulleys, and other devices for holding anddirecting the person's hair. These systems, however, are generally noteffective or applicable for persons with long hair and often cost asignificant amount of money to purchase and/or to maintain. Moreover,these automated systems require more time to set up the person havinghis or her hair washed, which is cost and time intensive. These systemsalso often cause discomfort to the person being washed as thoseaforementioned devices for holding and directing the person's hair alsotug and pull on it.

Furthermore, with most known sinks being attached to a wall of abuilding, the operator can generally only access the hair from two sidesof the sink body in order to clean and wash the hair. For those knownsinks that have a deeper opening than most standard-sized sinks, it isdifficult, if not impossible, for the operator to thoroughly access andclean a person with long hair without bending or twisting the operator'sbody in uncomfortable positions. This is often undesirable for manyoperators.

It is also generally known when washing a person's hair that hairfollicles sometimes become dislodged from their roots, subsequentlybecoming tangled or lodged in the drain area of a sink. For businessesthat intake a medium to high volume of clients, a hair washing sink thatprovides a client with quick, efficient, and quality cleaning isdesired. It is further desired to have a hair washing sink that isrelatively easy to maintain and provides quick clean-up resulting fromany debris generated from the hair washing process. As most of thoseknown sinks have the drain located above the floor of a buildingstructure, the operator is often required to physically remove anydebris or in some cases, dislodge hair follicles from the drain. This isoften done by using the operator's hands, or a towel or cloth, which isnot desired and in some cases, not sanitary. Those known sinks forwashing hair generally do not provide an effective and efficient way toclean the area where any debris or residue might build up by the drain,or an associated drain screen. As discussed, those known sinks forwashing hair are generally attached to the side wall of a building andthe draining area is above the ground surface of the building. As such,an operator generally cannot effectively use traditional cleaning tools,such as a mop or broom, to remove any dislodged hair or other debrisgenerated from the cleaning process.

In addition, many of those known systems for washing hair often requirethe user, or the chair in which the user is sitting, to be adjusted tothe appropriate height of the sink Most known sinks do not have theability to adjust themselves to the user without incorporating aseparate device independent of the sink structure. This is oftendesirable for situations where the functional limitations of bending thechair, or user, have been reached. Again, as those known sinks generallyextend from the side wall of the building from which they are attached,the operator is limited to placing the sinks along the side wall. Thislimits the sink placement locations for the operator in situations wherethe operator desires to have the side walls occupied by other objects,such as furniture and salon equipment, for example, or to have the sidewalls unobstructed entirely.

Therefore, a need exists to overcome the problems with the prior art asdiscussed above.

DETAILED DESCRIPTION

While the specification concludes with claims defining the features ofthe invention that are regarded as novel, it is believed that theinvention will be better understood from a consideration of thefollowing description in conjunction with the drawing figures, in whichlike reference numerals are carried forward. It is to be understood thatthe disclosed embodiments are merely exemplary of the invention, whichcan be embodied in various forms.

The present invention provides a novel hair washing sink with anelongated body to facilitate the easy and sanitary cleaning of longhair. Instead of being attached to and extending from the wall, as aretraditional sinks, in accordance with one embodiment, thepresently-inventive sink is freestanding. Due to the elongated bowl andlack of dependence on a wall for physical support, an operator of thesink advantageously now has the ability to maneuver around all sides ofthe sink and access the fully-extended hair of the person whose hair isbeing washed. The invention further provides the operator the ability toquickly and efficiently clean from the drain any residue generated fromwashing a person's hair. In addition, because the sink does notnecessarily need to be supported by a side wall of the building, thepresent invention provides the operator with more locations to place thesink.

Referring now to FIG. 1, one embodiment of the present invention isshown in a perspective downward-looking view. FIG. 1 shows severaladvantageous features of the present invention, but, as will bedescribed below, the invention can be provided in several shapes, sizes,combinations of features and components, and varying numbers andfunctions of the components. The first example of the hair washing sink100 illustrates the sink 100 having a body 102. Specifically, the body102 has a lower portion 104 that is coupled to a ground surface 106,i.e., the floor, of a building. The term “building” may be any structureintended for supporting or sheltering any use or continuing occupancyand includes structures such as salon, barber shop, or the home of anindividual. The ground surface may be any surface utilized by thebuilding for its occupants to travel across, but can also be an areabuilt up or lower than the actual walking surface of the building.

The lower portion 104 of the body 102 is formed at least partiallyaround a drain 110 and the body 102 extends upwardly from the drain 110to an upper portion 112. The body 102 can also be seen defining anopening 114 that extends upwardly from the lower portion 104 of the body102 toward the upper portion 112 of the body 102, thereby exposing thedrain 110 as well as substantially an entire interior 108 of the body102. A receiving area 116 is also shown located at the upper portion 112of the body 102.

The shape of the body 102 defines a water channel 118 that extends fromthe upper portion 112 to the ground surface 106, which may or may notinclude the drain 110. As the sink 100 is generally suited for thoseusers with long hair, the water channel 118 is an opening that containsthe hair when placed therein and advantageously allows the operator tofully extend the user's hair along the path of the channel 118. Theelongated water channel 118 obviates the problem with prior-art sinks,where longer hair is bunched at the base of the sink, sits in dirtywater, and covers the drain hole. The presently-inventive sink allowsthe operator to thoroughly rinse and clean the hair in its elongatedstate and further allows the hair to dry faster (i.e., excess water canbe squeezed out of it) than it would, had it been bunched up together orcollecting at the drain area of the prior-art sinks. Although the sink100 is suited for longer hair, those persons skilled in the art willstill appreciate how the novel features of the present invention applyto those users with shorter hair and the operators of the sink 100.

In one embodiment of the present invention, the body 102 extends to aheight 120 ranging approximately from 1.5 feet to approximately 3.5feet. In other embodiments, it is, more specifically, the receiving area116 which extends the total maximum height 120. Further, the assemblymay vary to a maximum height, indicated by reference number 120 in FIG.1, dependent on the location of the head/neck area of a person, alsoreferred to herein as a user. With the sink body 102 extending asufficient height 120 from the ground surface 106, the hair of the usergenerally never touches or reaches a lower portion 121 of the waterchannel 118 where the drain 110 is located, such that clean, washed,hair remains uncontaminated.

In one embodiment, the lower portion 104 of the body 102 is attached tothe ground surface 106 with bolts, screws, or other attachmentmechanisms. In other embodiments, the lower portion 104 is coupled tothe floor surface 106 using the concrete in the foundation of thebuilding, by the weight of the body 102, or by other couplingmechanisms. In the embodiment shown in the drawing figures, the body 102is supported by the ground 106 and does not rely on a side wall 122 ofthe building for physical support. As the sink 100 relies generally onlyon the ground surface 106 for physical support, this uniquely gives thesink 100 the ability to be placed in various locations within thebuilding and not just on the side wall 122. The various installationlocation choices advantageously give the operator placement options notgenerally available with prior-art sinks. Of course, the water supplywill be run through the floor to the inventive sink. The placementoptions of the sink also allow the user to access and clean the hair,and the drain, from behind the sink body 102. In other embodiments, thebody 102 may have portions that that are supported by the wall 122, butthe opening 114 would still generally be unobstructed by the side wall122 and advantageously continue to provide the operator with access tothe lower portion 121.

When the person's hair is placed within the water channel 118 theoperator carries out the rinsing and washing process. In one embodiment,the body 102 is formed at least partially around the drain 110, suchthat the runoff of water and other residue from the cleaning process isremoved. In other embodiments, the drain 110 is completely surrounded bythe body 102, as shown in FIG. 1. The side wall 124 of the body 102,also referred to herein as a “discontinuous” side wall, may completelysurround the drain 110. The term “discontinuous side wall” is definedherein as a wall that has at least one gap along the circumference ofthe wall. In other embodiments, the body 102, or discontinuous side wall124, is partially, as opposed to completely, overlapping the drain 110such that water is removed, but at a reduced volumetric flow rate. Infurther embodiments, the body 102, which again also includes thediscontinuous side wall 124, may not overlap the drain 110, rather ithas an opening around the lower portion 104 that delivers anyaccumulated water to the drain 110 located within the relativeproximity. In all embodiments, however, the drain 110 can be said to beplaced in fluid communication with the water channel 118. Thediscontinuous side wall 124 is formed to allow the water to flow to thedrain 110, but also reduces water or other residue generated from thecleaning process from exiting into the external environment surroundingthe side wall 124.

The opening 114 is illustrated as extending upwardly from the lowerportion 104 toward the upper portion 112, such that it exposes the drain110. An operator may now, advantageously, clean or access the drain 110area of the sink 100 to clean any residue or dislodged hair follicleswith traditional cleaning tools, such as a broom or mop. This isbeneficial as it does not require the operator to remove any debrismanually with his or her hands or any towels.

Now referring to FIG. 2, one embodiment of the present invention isshown. As shown, the drain 110 also includes a drain screen 201 coupledthereto. A drain screen 201 is generally known to those skilled in theart to catch larger objects than the formed apertures located on thesurface of the drain screen 201, such as residue and dislodged hairfollicles. In other embodiments, the drain 110 may not necessarilycontain a drain screen 201 or may have an adjustable drain plug thatwould allow water to enter, but exclude larger objects. To facilitatethe operator in accessing and cleaning the lower portion 104, theopening 114 has, and the side wall 124 defines, an elongateddiscontinuous gap 202. The term “discontinuous gap” is defined as agenerally horizontal opening that has a starting point and ending pointwhich both define an interval on a referencing structure, surface, orother object. In one embodiment, the elongated gap 202 is substantiallyunobstructed by the side wall 122 of the building to allow the operatorto effectively rinse a person's hair and also to clean the insideportion 121. In other embodiments, the opening 114 is also substantiallyunobstructed by the side wall 124 or a chair that the person, who'shaving their hair washed, is sitting in. As described, both the opening114 and/or the discontinuous gap 202 will be unobstructed sufficientlyenough for the operator to access the lower portion 121 of the waterchannel 118. In accord with one embodiment, the elongated gap 202extends from the ground surface 106 to the upper portion 112, or theheight 120 of the body 102. In other embodiments, the gap 202 is extendsless than or greater than the body height 120.

Also shown in FIG. 2 is the sink 100 having a base 200 that is coupledto the lower portion 104 of the body 102. As described above, the body102/side wall 124 is directly supported by only the ground surface 106.In other embodiments, the base 200 extends outwardly from the lowerportion 104 of the body 102 and provides physical support to the sink100. As shown in FIG. 2, the base 200 extends from, and is directlycoupled to, the lower portion 104 of the body 102. The base 200,however, may also be coupled above the lower portion 104 of the body 102such that the lower portion 104 can be inserted into a drain 110. Thebase 200 may also at least partially surround the drain 110, such thatthe lower portion 104 is coupled onto the top of the base 200 and waterpasses from the base 200 to the drain 110, as shown in FIG. 4. The base200 may be utilized in certain instances such as when the sink 100 iscoupled to the ground 106 with only its weight or when permanentcoupling mechanisms are not used or available. In one embodiment, thebase 200 and the entire body 102/side wall 124 are made out of a ceramicmaterial. In other embodiments, the above are made with a metallicmaterial, composites, resilient polymers, or other similar materialsthat are generally resistant to water exposure and capable of supportingthe weight of the head/neck area of the user. The base 200 may also beformed with any portion of the body 102 during the manufacturing processthrough injection molding or casting, depending on the material utilizedfor the body 102 and the base 200. In other embodiments, the base 200may also be coupled to the side wall 124 of the body 102 with adhesives,screws, or similar coupling mechanisms.

In one embodiment, shown in FIG. 2, the elongated gap 202 extends fromthe ground surface 106 to the upper portion 112 of the body 102. Inother embodiments, the gap 202 extends to an upper edge 205 of the body102. In such a configuration, the operator is provided with optimumaccess to the drain 110 and/or the drain screen 201 such that theoperator can clean and remove any debris the draining area. Moreover,the operator can efficiently access, rinse, and/or wash the longer hairof a person when the hair is fully extended within the water channel118, which was not available in most known prior-art hair washing sinks.

In further embodiments, the discontinuous gap 202 is further sized toallow a cleaning tool 203, such as a standard-sized broom (shown in FIG.2), to at least partially enter the gap. As such, the operator has theability to easily access to the lower portion 121 of the water channel118 to remove debris, such as dislodged hair for example. Generally, astandard-sized broom 203 has a cleaning portion 207, typically havingfibers, bristles, wire, or other filaments designed for cleaning, and ahandling portion 204, or a handle, that is typically parallel to thosefibers. Although the present invention references a standard-sized broom203 as being able to insert the opening 114, those skilled in the artcan still appreciate that any cleaning tool, such as a smaller handtool, may also be able to have access to the lower portion 121 of thewater channel 118.

In one embodiment, the gap 202 would be sufficiently sized such thatsome, or all, of the cleaning portion 207 of the broom 203 or any othercleaning tool is able to fit through the gap 202 in order have access tothe lower portion 121 of the water channel 118. This provides theoperator quick and efficient access to clean and remove debris from thedrain 110 and/or drain screen 201. In other embodiments, the cleaningportion 207 of the broom 203 enters at the upper portion 112 of the body102 and is able to access the drain 110 or drain screen 201 and forceany debris through the gap 202 or up and out through the upper portion112 of the body 102. In one embodiment, the drain screen 201 pulls upand out, for example, by pulling a cord or handle, for cleaning.

In other embodiments, the elongated gap 202 has one or more portions 210that prevent it from extending continually to the upper edge 205. Assuch, the body 102 completely surrounds the water channel 118 at thoseportions 210 along the height 120 of the body 102. As exemplified by thesection 210 in FIG. 2, the operator will still, advantageously, haveaccess through the gap 202 to clean or remove any debris at the drain110 or drain screen. Although the gap 202 is shown in FIG. 2 asextending from a top portion 206 of the base 200, other embodiments mayinclude the gap 202 extending to the ground surface 106 or where thedrain 110 and/or drain screen 201 is located. If the gap 202 extends tothe ground 106, then a section 208 (indicated with dashed lines) of thebase 200 may be removed to facilitate the removable of any debris.

In one embodiment, the gap 202 increases in width as the body increasesin height 120. In other embodiments, the gap 202 width may be a constantwidth, e.g., 6 inches, which extends upwardly from the drain 110 to agap height that equals the body height 120. In other embodiments, thelength of the gap 202 may be less than a total height 120 of the body102. In such embodiments, however, the width and height of the gap 202are typically sized sufficiently to allow access to the lower portion121 of the water channel 118, while simultaneously preventing asubstantial amount of the water, used in the rinsing/washing process,from escaping outside the side wall 124.

Referring now to FIGS. 3 and 4, two different embodiments of the base200 are shown from downward-looking perspective views. In oneembodiment, as shown in FIG. 3, the base 200 has a portion 300 adjacentto the discontinuous gap 202 and is substantially co-planar with thelower portion 121 of the water channel 118. Now, an operator may easilyclean and remove any debris around the drain 110 or drain screen 201with a cleaning tool 203. As such, the operator advantageously does nothave to remove any of the debris with his or her hands and/or with anytowels and may simply use traditional cleaning tools, such as a broom.

In other embodiments, the portion 300 of the base 200, as shown in FIG.4, is non-co-planar with the lower portion 121, such that the operatorwill be required to lift any accumulated or collected debris from thewashing process over an elevated surface 400. This embodiment, byplacing a height barrier in the drain area, helps prevent water fromsplashing out of the drain area during the hair-washing process.

FIG. 5 illustrates one embodiment of the present invention from a sidecross-sectional elevational view. The body 102 of the sink 100 can beseen having a front interior surface 500 below the receiving area 116that has at least a portion at a non-perpendicular angle, “theta,” withreference to the ground surface 106. The angle may be acute at certainsurfaces, perpendicular at others, and even obtuse in particularembodiments. As illustrated in FIG. 5, the interior surface 500 extendsat an acute angle from the lower portion 104 to the upper portion 112and is concave in nature, when viewed from the water channel 118. Thebody 102 allows the hair of a person to be supported by the surface 500when the hair is extended, as opposed to being wet and freely hanging,which reduces the tensile forces felt by that person. This beneficiallyprovides the added comfort to the person who is getting their hairwashed, while still preventing the hair from becoming contaminated withany residue from the cleaning process. Furthermore, the interior surface500 may also include ridges 502 or extrusions on which the operator canrub the subject's hair to produce a superior lather and overall bettercleaning process. In other embodiments, the interior surface 500 isangled acutely just below the upper portion 112, such that the hair issupported by the surface 300, and has a portion that is angled obtuselyjust above the lower portion 104, such that the hair is then freelyhanging. Moreover, the interior surface 500 may be perpendicular to theground surface 106 such that the hair is freely hanging when the user'shead/neck is in the receiving area 116. It should be understood to thoseskilled in the art that the body 102, including the discontinuous sidewall 124, may be formed in various shapes and with various curveswithout interfering with the spirit and scope of the present invention.

In one embodiment, the receiving area 116 is formed in the general shapeof a half circle such that it substantially contours a head/neck area ofthe user. The receiving area 116 may also have a polymer, foam, or othersimilar material that is coupled to the receiving area 116. Thisprovides superior comfort and support to the user's head/neck area whenplaced in the receiving area 116. In other embodiments, the receivingarea 116 is formed in alternative shapes or may be a designated portionof the upper edge that has no shape. In order to effectively allowrunoff from the hair rinsing and cleaning process, the receiving area116 is opposite to the base 200 or drain 110. In other embodiments, thereceiving area 116 may be located above or below the upper edge of thebody 102. As such, the user's hair is not required to be pulled throughan open aperture, such as those built into the prior-art funnel-likeapparatuses, nor is the hair required to rest and collect at the drainarea of the sink bowl.

Now referring to FIG. 6, an embodiment of a sink 600, in accordance withthe present invention, has a receiving area 602 extending upwardly pastthe upper portion 604 of the body 606. As such, the person would placehis or her head/neck in the receiving area 602 allowing the hair todrape and fall into a water channel 608. This feature alsoadvantageously allows the operator to accommodate those users withlonger hair. As an additional feature, the receiving area 602 may alsohave an extendable and retractable head/neck support assembly 610 inorder to comfortably adjust the user's head/neck area at an appropriateheight. As such, the chair that supports the user would not have toadjust to certain positions that are difficult, if not impossible, basedupon the structural limitations of the chair and/or the person whosehair is being washed. In one embodiment, the head/neck support assembly610 is incorporated into the body 606 or extends from a portion of theground surface 106, drain 110, or drain screen 201 that does notsubstantially prohibit the draining of water produced from the washingprocess. In other embodiments, the head/neck support assembly 610 is notadjustable. Further, in additional embodiments, the head/neck supportassembly 610 extends above the upper portion 604 of the body 606 or ispart of the upper portion 604/upper edge of the body 606.

FIG. 7 provides a perspective downward-looking view of a sink assembly700 that includes a water faucet assembly 701 coupled to the body 703.As the sink 700 may be freestanding and in close proximity to a wall,the water assembly 701 provides water to the operator. The waterassembly 701 generally includes at least a faucet 702, a hose or pipestructure (not shown) delivering water from a water source (not shown),and a valve 704. The faucet 702, hose, and valve 704 should also bewithin relative proximity to body 703 of the sink 700 such that thereare no hoses or pipes revealed or exposed on the ground surface 106. Thewater assembly 701 may integral with the body 703 or coupled to the bodyand hidden with a cover 706 that creates a generally more aestheticallypleasing appearance.

The hose or pipe delivering water to the faucet 702 may run through thebase 710, the body 703, or the ground 106 and extends upwardly towardthe faucet 702, which is generally located around the upper portion ofthe body 703. In other embodiments, the hose or the faucet 702 may belocated at, or coupled to, different locations along the body 703 andmay be extendable and retractable. When the hose is retractable, theoperator can maneuver the faucet 702 in various locations to effectivelyand efficiently clean and wash the user's hair while extended in thewater channel 712. In other embodiments, the body 703 may not have thewater assembly 701 attached thereto, such that the operator will usewater generated from another sink having a faucet or other water sourcewithin the building. The base 710 may also have an access panel 708located on it such that an operator can check the drain 712 area oraccess the hose for the water assembly 701. In other embodiments, thesink 700 may not have the access panel 708 or the panel 708 may belocated on other areas of the body 703.
